                        width="473" height="280">
                        <param name=bgcolor value="#FFFFFF">
                        <param name=movie value="mediaplayer/player.swf">
                        <param name=allowfullscreen value="true">
                        <param name=allowscriptaccess value="always">                        
                        <param name="flashvars" id="flash" value="type=http&file=test.flv&streamer=../xmoov.php&http.startparam=start&autostart=true&title=test&start=30">

                        <embed name="player2" id="player2"
                        type="application/x-shockwave-flash"                        
                        width="473" height="350"
                        src="mediaplayer/player.swf"
                        allowfullscreen="true"                        
                        allowscriptaccess="always"
                        flashvars="type=http&file=test.flv&streamer=../xmoov.php&http.startparam=start&autostart=true&title=test&start=30"> </embed>
